Abstract

Abstract:

To investigate the effects of photovoltaic array shading in agrivoltaic system on wheat yield, grain quality, and processing quality, a field experiment was conducted using the wheat cultivar Huaimai-33. Five treatments were applied: single-row adjacent panels (T1), single-row panels with east-west intervals (T2), double-row panels with east-west intervals and north-south adjacency (T3), double-row panels with intervals in both east-west and north-south directions (T4), and a control without photovoltaic panels (CK). The results showed that compared with CK, wheat yields under the four shading treatments were significantly (p<0.05) decreased by 35.34%, 30.08%, 19.05%, and 28.57% for T1 to T4, respectively, with the T3 treatment maintaining over 80% of the CK yield. In terms of quality, the T3 treatment performed optimally. Integrated assessment of agricultural and power generation benefits confirmed T3 as the optimal scenario. In summary, the T3 layout supports green, efficient, and stable wheat production in agrivoltaic systems, effectively balancing agricultural and photovoltaic power generation benefits, and provides a theoretical basis for the planning and design of wheat production in photovoltaic bases in Jiangsu Province.
